Re: [Haskell-cafe] Known Unknowns

Hey this is great. Chris your improvements are awesome. I mean the speed is nice, but you really cleaned up the code. There's an extraneous call to energy in the second runST block, but it should be insignificant. Also, -fglasgow-exts is necessary for the left-hand-side type declarations of size and dt. One question, in: calcMomentum (i+1) $! (px+vx*m,py+vy*m,pz+vz*m) that $! doesn't actually do much for a tuple, does it? Of course, there's not much point in further optimizing the initialization routine, as we'd never be able to detect the difference in runtime. The shootout has been a great learning tool for me :-) Thanks to Chris, Don, and the rest of the Haskell community. Joel
